As I write this, it appears likely
that there will be a muddy—or at least wet—track for the May 6 Kentucky Derby.
So how much is that going to affect who’s going to win? A lot. The only problem
for bettors is that at this point in their careers we don’t have much of an
idea of just who benefits and who suffers as a result of the mud.
Horses tend to be insecure about footing and very few
actually like running on a wet track. But some mind it less than others and
will turn in a performance as good as their usual. That’s often enough to win
over a better horse who is less comfortable on muddy surface.
Most of the 20 horses expected to start in the Kentucky Derby
have limited racing experience in general and even less experience racing on
wet tracks. Eight (including the morning line favorite Classic Empire) have won
on off tracks, but only Gormley has won a stakes race in the mud.
In lieu of actual experience on wet tracks, handicappers look
at the wet-track success of the parents, particularly the sire, since ability
in the mud is sometimes, but not always, inherited. There are a number of ways
to analyze wet-track pedigrees, but the most respected system—that of Lee
Tomlinson—gives the nod to Irish War Cry, Tapwrit, and McCraken.
One other fact to keep in mind: sometimes a horse who
otherwise can’t handle the mile and a quarter distance of the Kentucky
Derby—one who speeds away from the gate to an early lead and is likely to get
caught in the stretch—can sometimes persist on a muddy track. It’s probably a
function of avoiding the mud thrown back from horses in front. A likely early
leader is Irish War Cry, interestingly the horse at the top of the Tomlinson
ratings for wet-track pedigree. On the other hand, Irish War Cry has a terrible
post position. Battle of Midway also
qualifies on both fronts. He has a high Tomlinson rating and likes to run on or
near the lead.
Of course, this works the other way too. A horse like Gunnevera,
who is expected to come from off the pace, may have trouble making up ground
late in the Derby.
Remember that both the weather and horses are fickle. The
track may end up fast and the horses may run nothing like they are expected to.
That’s horse racing--and that’s what makes it interesting.
